Comment # 2 on bug 1206850 from Stefan Br���ns

If the users want to print these documents, they also need:
1. All referenced fonts
2. A postscript processor
3. A printer

Of the 3, only ghostscript is Required.

DVI is not an exchange format, and DVI with embedded metapost outside of an
processing pipeline is absolute niche.

If a user wants a full pipeline with metapost capabilities, there is
texlive-collection-metapost.

There is nothing wrong with putting metapost as Recommended, but Requiring it
is just incorrect. metapost is probably the only optional dependency which is
made a hard dependency - there is no hard dependency on hyperref, though the
latter is definitely more often used by TeX users than metapost.
